Subject [jira] [Updated] (NIFI-480) Pressing escape to close/cancel a dialog does not work in all conditions
Date Wed, 01 Apr 2015 13:49:54 GMT

Matt Gilman updated NIFI-480:
-----------------------------
    Attachment: 0001-NIFI-480.patch

This patch addresses concerns when pressing escape to cancel a dialog in the canvas and controller
settings. Known remaining issues to be addressed separately.

- Pressing escape does not currently work in other pages (Summary, History, Users, etc).
- When editing a property value, if the field loses focus the ability to escape is lost until
the focus returns. This is due to issues with the grid's editor being able to clean up after
itself. Once focus is lost, the event bubbles outside this context and could lead to canceling
the entire dialog. This could lead to configuration loss if there were other unsaved changes.
For this reason, it is prevented.

> Need to ensure the proper closing when the dialogs become stacked. This is very tricky
due to other components grabbing focus and throwing off the event bubbling.
